摘要
We have measured elastic scattering and peripheral reaction channel cross sections for the O-16,O-18 + Ni-58 systems at E-Lab = 46 MeV. The data were analyzed through extensive coupled-channel calculations. It was investigated the consistency of the present analysis with a previous one at sub-barrier energies. Experimental fusion cross sections for these systems are also compared with the corresponding predictions of the coupled-channel calculations. (C) 2004 Elsevier B.V. All rights reserved.
